Blog themes

I am toying with the idea of adding weekly themes to my blog, like Word filled Wednesday, Thankful Thursday, or Fun-filled Friday, maybe one to do with parenting. I think it would give the blog a little more focus and enable me to have direction about what to write in times of boredom. I would like to start with thanksgiving since it would put my focus on God and not on me and what I do not have. What do you think about this idea?
